Yang Chen could not fathom it. By all rights, no step should have gone wrong. But what exactly was happening?
"Where exactly..." As Yang Chen precisely refined the pill, he desperately searched for the step where he had gone astray.
After all, even he did not dare guarantee that after such extremely high-density refinement, not the slightest error would occur.
Very soon, Yang Chen suddenly thought of something. "Could it be an issue with the heat when the final ingredient was added?"
The moment he thought of this, Yang Chen's entire body trembled.
This was likely a point that would be very difficult for him to resolve.
It was not that there had been a problem with the order in which he added the ingredients. Rather, controlling the heat was exceedingly difficult and required utmost precision. At the time, he had been off by just a tiny thread—only a tiny thread.
He had originally believed it would not cause any problems, yet it seemed that this was precisely why the liquid now could not solidify into pill form.
For a moment, Yang Chen grew anxious and unsettled.
If he remained trapped in this cycle with no way out, then his pill refinement could basically be declared a failure.
How could Yang Chen accept that? These materials had been incredibly complicated to gather. He had used up quite a few of the materials he had obtained from the Black Demon Clan's material storehouse, along with those taken from the tomb, and had only barely managed to assemble enough for one furnace of Nine Nether Immortal Pills.
